<p class="MsoNormal">Hi,<br>
<br>
That command is just setting an acl for that IP to connect to the gluster daemon.<br>
<br>
Normally you don't need to add any IP addresses as glusterfs clients will know about both servers as soon as they connect to one of them. If you're using Samba or NFS the preferred option is to use CTDB to spread a pool of virtual IP addresses over the servers.<br>
<br>
